I have an asp page that has an iFrame. In the onload event of the iFrame, the javascript code copies the content of the iframe to the div. The iFrame has src="test.aspx" and hence displays the content of the test.aspx inside the div.Test.aspx page contains and imageButton, which does not show up in the iFrame.I am getting the following issues:1. the image does not show up (cannot see test.gif)2. When i click on the imagebutton link, it tries to search for test.aspx in the directory where the asp page resides inside of the actuallocation/directory of the aspx page.
View 3 RepliesI have an imagebutton in Gridview control which is placed in ajaxtoolkit:TabPanel. Clicking on the imagebutton for the first time works fine. It posts back and does the desired action. However, when IsPostBack is true, it doesn't work. Even the onclick event is not called although the page posts back. Please help. Given below is the code for the same:

How do I set the CommandArgument? The above code does not work and how to do this.
For a given MS SQL Database table of staff members, I'm using ASP to display each record line by line as follows:
So I've added 2 ImageButtons in an extra column and the problem I have is passing the record id as a CommandArgument to redirect to a secure page where the record can be edited or deleted.
Here's some code:
[Code]....
[Code]....
ctdRdr(0) evaluates to the ID value for the the record. )
When I click on the 'Delete' ImageButton the URL in the Response.Redirect becomes:
ctdirectory_secure/deletemember.aspx?id=<%@%20ctdRdr(0)%>
instead of, say:
ctdirectory_secure/deletemember.aspx?id=435
I'm assuming that a <%= expression %> cannot be used to set a control parameter, but how else can I do it?
I created a form in a popup div, that contain an UpdatePanel with ImageButtons in it.Initially, I used LinkButtons to test but I wanted ImageButtons. The thing is, it works well with LinkButtons and not with ImageButtons (absolutely nothing happens).
<a href="javascript:WebForm_DoPostBackWithOptions(new
WebForm_PostBackOptions("ctl00$cphC$ctrlAdr$AdrMapo$lbAdresseSaisie",
"", true, "",
"", false, true))"
id="ctl00_cphC_ctrlAdr_AdrMapo_lbAdresseSaisie">test</a>

I'm trying to use the ImageButton control for client-side script execution only. I can specify the client-side script to execute using the OnClientClick property, but how do I stop it from trying to post every time the user clicks it? There is no reason to post when this button is clicked. I've set CausesValidation to False, but this doesn't stop it from posting.
View 3 RepliesI have a UserControl with a ModalPopupExtender that shows a Panel with a GridView. I use this UserControl inside an UpdatePanel.The issue is that I'm using a LinkButton in a TemplateField of the grid that sends a Command and it is working well. If I replace the LinkButton with an ImageButton, the AJAX call raises an error 500 (and I don't know how to debug it). As I understand, the ImageButton will send the same CommandName to the same OnRowCommand handler as the Linkbutton.
View 2 RepliesI have a very simple page consisting of a number of imagebuttons that when pressed should change the text in a label.To get a rollover effect I have placed these three lines in the "Page_Load" routine for each button:

This works like a charme in Firefox, but in both IE and Opera nothing happens when the imagebuttons are pressed?I must be missing something obvious here, but what?
Why isn't the image displayed? The folder images is in the same folder as the .aspx file.Why doesn't it invoke the ImageButton1_Click method when I click on the image? The OnClick should be for the server side.The ImageButton1_Click method takes 2 parameters, but why OnClick does not require 2 parameters?
<asp:ImageButton
ID="ImageButton1"
runat="server"
ImageUrl="images/export.gif"
OnClick="ImageButton1_Click"
/>
protected void ImageButton1_Click(object sender, ImageClickEventArgs e)
{
Label1.Text = "You've clicked the image button.";
}
I have to add this line to the Page_Load method in order for it to invoke the ImageButton1_Click method when I click on the image, why?
ImageButton1.Attributes.Add("onclick",
"ImageButton1_Click()");
This line works fine too:
ImageButton1.Attributes.Add("onclick",
"ImageButton1_Click('report.xls', GridView1)");
The 2 parameters are: object sender, ImageClickEventArgs e. What are they and why I pass in a string and a gridview, which I don't think match with the arguments definition, and it still works?
I have embedded an ImageButton inside a GridView.Now I am using a loop to just make the ImageButton visible on the first row and that works great. I use the FindControl to do that and are also putting an Image to that button on the first row.Now is my problem this that this button also needs to have an URL attached to it so when pressing this button it will be possible to open up a Browser with this URL attached to it. I need to use the code that I have in the ImageButton6_Click event as this code is working with IE, Firefox etc... It seems that I should have gotten this correct but dont know why the ImageButton6_Click event isnīt firing when pressing the button. What I get is an Errorpage that says "Invalid postback or callbak argument" etc...

I am a new to WCF. I have written ajax to use a web service before, but on this project I am trying to use ajax to WCF.After I build the project and wcf using ajax, I receive the return successfully. But, 10 or more minutes later I don't get a return, the ajax calls the error function, and the fiddler returns nothing.
If I rebuild the project without any source modifying, I receive the return successfully again.
I have an img control that I am trying to replace with an image button.

I'm trying to do: I have a webform with a datalist. The datalist shows projects (projectname, image and an imagebutton). When a visitor clicks the imagebutton two events should take place:
- First: data should be send to SQLdatabase (projectID, name of project, sessionID, datetime etc).
- Second: a pop up window must be opened to an existing webpage of the facilitator of the project, using an url which (is in my database).
The problem is my two seperate pieces of code-behind work fine, it's just that they won't work together. Here is my code: The imagebutton:
< asp:ImageButton ID="openButton" CssClass="openbutton" runat="server" ImageUrl="~/Images/openButton.png" CommandName="Sendto" CommandArgument='<%#Eval("ProjectID")%>' OnDataBinding="openButton_DataBinding" ></asp:ImageButton>
Code behind send to database:
protected void list_ItemCommand(object sender, DataListCommandEventArgs e)
{
if (e.CommandName.ToString() == "Sendto")
{
string projectId = e.CommandArgument.ToString();
bool succes = ProjectAccess.Projectopen(projectId);
}

I am trying to save an updated xml file to a url like this:
Quote:
//save the output to a file
xmlDoc.Save("http://www.example.com/HomeNewsLinks.xml");
But I get this error: URI formats are not supported.
Did some google search on this and it seems I need to use client.uploadFile method, but I am not able to find how to declare/define filenamexxx (below) and how to pass a username/password.
Quote:
WebClient Client = new WebClient();
Client.UploadFile("http://www.example.com/HomeNewsLinks.xml", Post, filenamexxx);
I used this,

I am following though the examples in Professional ASP.Net MVC 2 and one of the examples doesn't work for me.
[HttpPost]
public ActionResult Edit (int id, FormCollection collection)
{
Dinner dinner = dinnerRepository.GetDinner(id);
if (TryUpdateModel(dinner))
{
dinnerRepository.Save();
return RedirectToAction("Details", new { id = dinner.DinnerID });
}
return View(new DinnerFormViewModel(dinner));
}
I understand that it's suppose to take the values from the FormCollection, and then update the dinner object with it, bit I don't see the collection get referenced anywhere.

I have a listview in which I use a pager control. When I have more than 1 item in the list view, I want the user to be able to click on the appropriate page number and go to it. Simple right?, right now the first time the user clicks on the page number, nothing changes. If they click on it again, it goes right to the page. It doesn't matter what page they click on, it ALWAYS requires a second click to display the data item.
I am using VS2010 C# as the code behind.
I know that UpdateProgress doesn't work with PostBackTrigger, but let me explain what i'm trying:
I'm generating a PDF document (Crystal Report) with ExportToHttpResponse that will be downloaded automaticaly by the browser.
So while the document is been generated, i'd like to show the UpdateProgress just while i'm waiting the doc is being generated, doing the UpdateProgress(or some label) to disappear.
